1. Nightly Rust and Conc

The conc library depends on an unstable Rust compiler feature and won’t compile with a recent stable Rust version. The last update to conc and its parent project was in August 2017. To use it, you need a nightly Rust version from that period. If you’re using rustup , you can switch to nightly-2017-08-17 easily. Remember to switch back to a modern Rust version after you’re done.

1.1 Exercise Program for Hazard-Pointer Treiber Stack

We’ll test the performance of the conc Treiber stack. Key areas of interest are:
- Push/pop cycles per second
- Memory behavior and high-water mark
- Cache behavior <
